An unspecified error occured during system restore 0x800700b7

Hi,

·        How are you trying to do a System Restore, through Windows Recovery console?

·        Are you able to boot into Safe mode?

·        Do you remember making any changes to the system?

If you are able to boot into safe mode then I would suggest you follow method 1.

Method 1:

Follow the steps mentioned below to perform a clean boot.

1.      Click Start, typemsconfig.exe in the Start Search box and then press ENTER to start the System Configuration Utility.

2.      On theGeneral tab, click Selective Startup and then click to clear theLoad startup items check box. (The Use Original Boot.ini check box is unavailable.)

3.      On theServices tab, click to select the Hide all Microsoft services check box and then clickDisable all

 Note: Following this step lets Microsoft services continue to run. These services include Networking, Plug and Play, Event Logging, Error Reporting, and other services. If you disable these services, you may permanently delete all restore points. Do not do this if you want to use the System Restore utility together with existing restore points.

After you have finished troubleshooting, follow these steps to reset the computer to start as usual:

1.      Click start, typemsconfig.exe in the Start Search box, and then pressENTER.

If you are prompted for an administrator password or for confirmation, type your password, or click Continue.

2.      On theGeneral tab, click the Normal Startup option, and then click OK.

3.      When you are prompted to restart the computer, click Restart
